Appie Knoll is the kind of suburb where kids grow up right. But something is wrong. Fourteen-year-old Kevin Bartlett disappears. Everyone thinks he's run away — until the comic-strip ransom note arrives. It doesn't take Spenser long to get the picture — an affluent family seething with rage, a desperate boy making strange friends... friends like Vic Harroway, a bodybuilder. Mr. Muscle is Spenser's only lead, and he isn't talking—except with his fists. But when push comes to shove, when a boy's life is on the line, Spenser can speak that language too.
